STOP-MOTION FoR' LOOMS.

Specification of Letters Patent.

Patented Feb. 26, 1907.

Application filed February 14, 1906. Serial No- 300,953.

To all 1072,0717 it may concern.-

Be it known that I, THoMAs THOMPSON, a citizen of the United States,residing at Central Village, in the county of Windham and State ofConnecticut, have invented certain new and useful Improvements inStop-Motions for Looms, of which the following is a specification,reference being had therein to the accompanying drawing.

My invention relates to that class of stopmotions for looms which isoperative upon the fracture of a portion of the loom mechanism, and hasfor its object the ends commonly sought in this class of mechanisms; butmore particularly is it sought to avoid the fracture or other injury tothose loom parts which are adjacent or contiguous to the broken member.

A -further object is to prevent the continued picking or-other action ofthe loom after a break which renders the harness inoperative.

To the above ends, essentially, my invention consists in anautomatically-operative connection adjacent to and operated by thefractured part actuating the shipper-rod.

In the drawings, which constitute a part of these specifications, and inwhich like characters of reference indicate like parts, the figure is aperspective view of my novel mechanism embodied in an ordinary loom,such parts only of the latter being shown as are pertinent to theinvention involved.

The loom herein shown for the purposes of illustration comprises thefollowing usual parts:

A is the frame; B B the front and rear arches, respectively; C and C,the upper and lower cylinder-gears; D, the vibratorgear, supported bythe vibrator-lever E.

1* is one of the jacks, and G the vibratorconnector.

H is the lay, provided with a hunter I, and J is the shipper-rod,carrying the shipper handle or lever K. Upon the rod J is mounted afinger L, to whose end is pivoted a dagger M, whose free end is normallybelow the line of travel of the hunter.

Pivotally mounted in the arches below the vibrator-connector G is ahorizontal wire rod 1 N, having the portions adjacent its endsrectangularly bent or arched, n. The bent or arched bar N is normallyupwardly inclined, but is adapted to swing downwardly into asubstantially vertical plane by light pressure or impact thereon fromabove. Pivotally attached to the rod N is a vertical connecting-rod O,whose lower extremity is connected to the inner end of a horizontal wirelever P, pivoted intermediate its extremities by a pivot-pin Q in theloom-frame. The outer end of the lever P is upwardly inclined, p, andprovided upon its extremity with an eye or opening 79, through which thedagger M passes. In order not to obscure the novel parts, only one jackand vibrator-connector are shown. The lever P and parts of the rod O anddagger M- are shown in broken lines.

The operation of my novel mechanism is as follows: If and when thevibrator-connector breaks, as is a comparatively frequent occurrence,one of the broken parts forthwith presses the inclined bar or rod Ndownwardly into a substantially vertical position, thereby through theconnecting-rod O elevating the outer end of the rod P and raising thepoint of the dagger M into the line of travel of the hunter I, wherebythrough the finger L the shipper-rod J is rotated to stop the loom.

Having described my invention, what I claim is 1. In a loom, thecombination with the vibrator-connectors of movable means adj acent theconnectors and adapted to be operated by a broken connector, andstopping instrumentalities actuated by the movable means.

2. In a loom the combination with the vibrator-connectors, of pivotalmeans adjacent and below the connectors, and adapted to be swung by abroken connector, and stopping instrumentalities connected with andactuated by the pivotal means.

3. In a loom the combination with the vibrator-connectors of a bent rodpivotally mounted below and adjacent the connectors, means for shiftingthe shipper, and connections between the bent rod and shipper-shift ingmeans.
